FAQ

1. What is custom in-ear monitors (CIEM)?
   
   It is completely individual earphones produced by using your ear imressions.
   
2. What is the ear impression procedure? Is it hurt?
   
   Ear impression procedure takes 5-7 minutes. First of all, a specialist checks the ear canals for foreign bodies (cerumen). Further a cotton block that will prevent impression material leaking to the eardrum is placed into the eardrum cavity. After that a silicone viscous mass is filled in the ear canal hardened within 3-4 minutes. The mass is ejected after a complete solidification. This is your ear impressions! The process is completely painless and safe. You feel only a slight distension on the entire surface of the ear canals.
   
3. What to do with my ear impressions?
   
   Ear impressions should be sent to our lab by the mail service. Also you can downlowd your ear impressions in stl* form in your user account on our web.
4. What is the term of production at the Ambient Acoustics laboratory?
   
   Terms of production of monitors is 3-4 weeks after the moment of receiving impressions and payment confirmation. For plugs and tips the time of production is 2-3 weeks after the moment of receiving impressions and payment confirmation.
   
5. If it will be uncomfortable for wearing my customs, can the shape be changed?
   
   If customs are pressured in any place of the ears, their shape is corrected successfully. Contact us for more information!
6. Do we save ear impressions or send them back with the order?
   
   All impressions, starting from June 2018, are stored in 3D form in our lab. We send you back ear impressions with your product. Also you can buy ear impressions in stl* form.
   
7. If I already have my ears impressions, can I order the production of individual products according to them?
   
   If you already have your ear impressions we can make our individual products according to them. However, the impression material (silicon) gives some form of shrinkage and casts form is changes over time. That is why, we take into the work casts no longer than 6 months old!
8. If after monitors’ production I don't like sound, has it no possibility to correct it?
   
   Products for sound correcting are not accepted! It is advisable before ordering Ambient Acoustics monitors become familiar with the sound of the model that you are most interested in!
   
9. What is the period of adaptation to CIEM and individual products?
   
   Period of adaptation to the custom monitor, tips, earplugs is 10-14 days. Only after the expiration of this period products are taken for shape correction!
   
10. If I suffer from a chronic otitis, can I use the individual custom monitors or tips?
    
    If a person suffers from chronic discharge from the ears, the usage of individual custom monitors can lead to acute inflammation. This is because the individual monitor shells blocks the air access into the ear canal (canal is not ventilated), which leads to an increase of bacteria in the ear during prolonged use. Also, discharge may enter into the speakers of monitors leading to their failure. In these cases, the use of additional waxguard filters on the monitors is more than desirable.
    Consult Your ENT specialist about the possibility of using such products!
11. What are the most frequent breakdowns occur with monitors?
    
    If you have any problems with the monitors, such as sound intermittency, sound absence in one ear the problem may be in the cable or connectors, but not in acoustics of monitors themselves. To solve this problem, disconnect the cable where it is connected to the monitor. Change position of the left and right monitors. If the problem persists, then the fault is either in the speakers, or in acoustic filters.
    
    If the music does not sound clear and quiet, this is a problem of acoustic filters’ pollution. Acoustic filter is a mesh that has the necessary acoustic impedance. It is placed in a sound bore monitor. If the filter mesh gets wet or dirty, the sound “permeability” is deteriorated. It distorts the sound picture. To solve this problem, place the monitor in a sealed container (or box) with an absorbent material (eg – silica gel). If after a few days the problem is not solved, please contact us for further instructions.
    
    If the music sounds distorted (metallic echo, rattling, strong distortion), it is a clear sign of the speaker (-s) failure. Moisture which gets into speakers by the sound bore or mechanical effects (drop, kick, etc.) often causes the break-down of speakers. In this case, carry out the same procedure with silica gel and if it does not be a successful one, contact us shop@ambient-acoustics.ua
    
12. Do I need a special equipment for CIEM functioning?
    
    If you listen to music, simply connect the Ambient monitors to any MP3 player or portable media. If You're on stage or repetition you need a wireless radio system.
13. What is custom tips?
    
    It is completely individual tips, which put on your earphones. They are produced by ears impressions.
14. Silicone or acrylic? Which is better for tips?
    
    Silicone is mainly used for the removable custom tips on earphones or communication headset production. Due to its flexibility and structural strength, it is easy to apply the sound bore earphones form stretching, thereby fixing the tips well. You can remove such tip at any time. Acrylic material is solid, so it is used only for fixed tips production. From the point of comfort, it is more convenient to use acrylic. The silicone material has a high level of porosity, so if you suffer from a profuse discharge out of ears, it may lead to the development of bacteria in the silicone pores. Which can lead to the material “decay”. From the standpoint of a sound, no objectively measured differences have been discovered!
15. Is there a big difference in sound between custom tips on the universal earphones and full customs?
    
    The difference is not big, but still it is present. Thanks to placing speakers closer to the eardrum full customs provide greater sound insulation in comparison with the tips, it creates a subjective earphones’ volume increase, thereby increasing the perception of low-frequency range. Resonance of the sound bore in the tips is located in the upper middle frequencies, while in the full custom it is located at high frequencies. Thus, due to this, and based on the speakers characteristics, with full customization it is possible to achieve more linearyty in FR than using custom sleeves on universal IEM! However, subjectivity will always be present in this matter, based on the sounds personality perception of different people!
